| | '''OpenGL extension ARB.half_float_vertex |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.ARB.half_float_vertex to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension extends the usage of the half-precision (16-bit) floating- |
| | point quantities introduced in ARB_half_float_pixel for usage in specifying |
| | vertex array data. |
| | |
| | This extension allows applications to use half-precision floating point data |
| | when specifying vertices. This can allow applications to reduce their |
| | memory footprint, as well as the memory bandwidth required for vertex data. |
| | |
| | This extension extends the existing vertex array commands to accept the new |
| | data type. |
| | |
| | |
| | The official definition of this extension is available here: |
